Abstract

In allusion to subjectivity and inaccuracy of intersection line of faulted coal seam by connecting the fault control points directly, according to the V-like rule, a method of Boolean intersection operation on fault surface and the trend of coal seam was put forward to get the intersection line of faulted coal seam. On the basis of the fault control points and fault lines data, the fault surface model was built. On the basis of quadratic polynomial model, index model, the Gompertz model, coal seam section curve on the edge of the faults was extended in terms of trend of coal seam, coal seam trend surface model was built. Through Boolean intersection operation on fault surface model and coal seam trend surface model, the intersection line of fault coal seam by the constraint fault surface together with coal seam trend surface was got. Compared with the intersection line of faulted coal seam by connecting the fault control points directly, the results showed that the intersection line of faulted coal seam by the constraint fault surface together with coal seam trend surface fully considers the trend of coal seam on faults, more veritable responses space form of intersection line of faulted coal seam, it has important theoretical and practical significance in the aspects of establishing solid models of coal seam and guiding the actual production.
